: I am trying to find out where the Hepatitis shot comes from (i.e. plant, animal, etc.) also MMR. If anyone knows the answer to this can you please post the information or lead me to where I may be able to obtain these answers. Thanks in advance.

REPLY; Try the info at www.909shot.com IMO as far as I know, no vaccines come from plamts, they are treated virus'es, either half killed or fully killed, then injected into an animal or blood supply. Have no idea if human bloods are used or just animals. After injecting into the animal of choice, it makes anti-virus fluids by it's white blood cells which results inan immune marker in the serum. This is..probably processd more...then treated with some kind of heavy metal containing 'gunk' as a preservative, then it's ready to serve up to your kid. That's jus MY idea of he processes but think 909shot will av lots of info. Grandma Peg
